Millionaire Mystery Box opinion
Big Time Gaming has had some winners of late, including my favourite Bonanza that features their Megaways mechanics. I’ve become a fan of this developer’s high volatility games as I find them innovative and highly entertaining.
On the surface, this slot has the potential to be an exciting game because of its high volatility and a good assortment of features. Sadly, gone is the Megaways mechanics that I’ve gotten used to, as BTG has opted for 243 ways to win.
While the slot does have several features, I was disappointed with my average win value, despite several hundred rounds of play. I found it particularly difficult to crack 10x total bet, and the extra spins were no guarantee although, in theory, we stand the best chance of hitting 12,000x total bet – just don’t hold our breath! We’ll need to have a higher risk appetite and patience to play this slot.
Unwrapping the Mystery

Millionaire Mystery Box is a high volatility slot with an RTP of 96.642%.
Millionaire Mystery Box – Game overview
The slot, released in 2019, is designed to create a vintage atmosphere. It is based on the popular international television show where players choose from amongst multiple choice answers to win large sums of money. It is a follow-up to the 2018 release of Who Wants to Be a Millionaire. In fact, we’ll find that the appearance is very similar.
The slot uses a diamond as the highest-value symbol which rewards a win with as little as two symbols on a payline. From there, we’ll find three uniquely coloured and geometrically shaped symbols acting as the middle-value. Finally, the 9 through to ace royal flush poker icons represent the lowest-paying symbols. The music in the game is what we’ll find on the television show, which gives the slot an even more genuine feel.
The game can be played with bets of as little as £0.10 and as much as £40, and has an RTP of 96.642%. Furthermore, it is optimised for mobile, tablet and desktop play, so we need an Android or iOS when in motion.
Game features of Millionaire Mystery Box
2x Multiplier Wild
The 2x multiplier wild may appear on the second, third and fourth reels and substitute for all symbols except the scatter. All winnings for which it takes part are multiplied by two.
The game is a follow-up to 2018’s Who Wants to Be a Millionaire.
The Mystery Box may appear on the second, third and fourth reels. The boxes open to reveal an alternate but identical symbol. This enhances the chance of creating larger wins.
Ladder Gamble Feature
The ladder gamble feature is triggered after any winning round. It allows us to play for double or nothing, up to 5 times.
The slot features a Mystery Box, ladder gamble feature, 2x multiplier wild, scatter wins and extra spins with up to 50x multiplier.
Extra spins with Progressive Multiplier
The extra spins game is awarded by getting 3, 4 or 5 scatter symbols for 7, 12 or 20 extra spins. The scatters will award 2, 5, 20 or 200 coins with 2, 3, 4 or 5 symbols respectively.
Once triggered, a multiplier ladder with 12 rungs appear. The multiplier ladder on the first, second or third rung is triggered by 1, 2 or 3 scatters respectively. Each scatter symbol increases the multiplier ladder by a rung which translates into additional extra spins and greater multiplier as follows:
- 1st scatter: 3x multiplier + extra spin
- 2nd scatter: 4x multiplier + extra spin
- 3rd scatter: 5x multiplier + extra spin
- 4th scatter: 6x multiplier + 3 extra spins
- 5th scatter: 7x multiplier + extra spin
- 6th scatter: 8x multiplier + extra spin
- 7th scatter: 10x multiplier + extra spin
- 8th scatter: 12x multiplier + 3 extra spins
- 9th scatter: 15x multiplier + extra spin
- 10th scatter: 30x multiplier + extra spin
- 11th scatter: 50x multiplier + 3 extra spins
